Mongo db - Interroger un tableau imbriqué d'objets

Question

Je suis vraiment aux prises avec la construction d'une API REST avec les données que j'ai ci-dessous, tout fonctionne bien du côté client mais quand j'ai besoin de faire des requêtes POST pour mettre à jour players je n'arrive pas à comprendre comment interroger mongodb.

La route

router.get('/api/teams/:teamid/player/:playerid', player.getById); 

La requête mongodb

module.exports = { 
    getById: function(req, res) { 
     models.Team.findOne({"players.player_name":"Jokim"}, function(err, player) { 
      if (err) { 
       res.json({error: 'player not found.'}); 
      } else { 
       console.log(player); 
       res.json(player);  
      } 
     }); 
    } 
}; 

Les données Json

Answer 1

Comme vous essayez de Rechercher dans les tableau joueurs je pense que vous devrez utiliser elemMatch:

S'il vous plaît trouver les documents liés à la même: http://docs.mongodb.org/manual/reference/operator/projection/elemMatch/

PS: Je ne l'ai pas essayé ce que je n'ai pas NodeJS avec Mongo sur mon système maintenant .

Answer 2

Habituellement, les gens utilisent la méthode PUT pour mettre à jour le modèle.
Vérifiez la méthode update dans les documents mongodb.

Route

router.put('/api/teams/:teamid/player/:playerid', player.updatePlayer); 

Contrôleur

module.exports = { 
    updatePlayer: function(req, res) { 
    models.Team.update({"players.player_name":"Jokim"}, {$set: {assist: 100}}, function(err, player) { 
     if (err) { 
     res.json({error: err}); 
     } else { 
     console.log(player); 
     res.json(player);  
     } 
    }); 
    } 
};
